[SOLVED] New MySensors appearing with random values

[velkrosmaak]

I'm using the standard Serial Gateway setup, going into Domotiga running as a VM. I have one sensor running this sketch I mashed together from two of the examples (PIR and the BMP180 sketch). This works fine, the PIR, temperature, and pressure appear as 3 sensors. I've built another MySensor, running the sketch in this thread: http://forum.mysensors.org/topic/1006/my-motion-dallas-light-sensor

After a seemingly random interval, additional MySensor devices begin appearing in Domotiga. Here's an extract of the log - this is when a new sensor appeared in Domotiga.

I don't understand why it's creating these additional devices. I've checked the serial output of both of the arduinos, and I can't see anything relating to this in the output.

Any help would really be appreciated! :) Thanks! :beers:

Version and type of gateway?

If you're sending a float value to an older gateway it had problems converting it to a string.

Hi hek - thanks for the reply!

I'm using the serial gateway, with an arduino nano as per this example: https://www.mysensors.org/build/serial_gateway

The sketch is straight from the MySensors library - version 1.5 from the site.

And if you look at the debug log on the node, what is it actually sending?

[velkrosmaak]

You mean the output on the serial monitor? I'm not at home at the moment so can't provide you with the output, but I don't recall seeing any values outside of the expected range (for temperature, light, and movement). I can provide this when I'm back.

Starting to think that it might actually be my first node that's causing this. One of the 'random' values does match the pressure value of the first sensor on occasion - I wonder if there's actually a transmission issue. I did hack that sketch together myself, so it could well be that. Couldn't find an example sketch for PIR and BMP180.

[velkrosmaak]

For my own sake of closure, I wanted to share that it does appear to have been my bodged together PIR/BMP180 sketch that was causing the issue - but only when in combination of an additional sensor node. Missing closing bracket somewhere or something.

Thanks for the help!

Great that you got it working. Thanks for reporting back.
If you don't already know, ctrl+t (or cmd+t) on the Arduino ide auto-indents the code. That can often make it easer to spot wrong brackets.
